Flipper was born with a twisted spine. She's not paralyzed, but the brain signals to her back legs don't translate into proper movement for the real world. Vets at the Aspen Park Vet Hospital in Conifer, Colorado, considered pitting her down, but then decided to seek the help of the Blitz Robotic Club at Conifer High School.
Club members—some of whom love cats—developed three prototypes that acted as hind legs for the furry feline. She gets into a harness, which helps her stay erect, then with hind legs pumping Flip begins motoring around the clinic.(via Arbroath)
“This is just the neatest thing,” said Jan Gurney. “She loves kicking her back legs to help power the cat-traption around, it gives her so much mobility and in time her legs will get stronger and her spine may also loosen up to allow for her to one day get around on her own.”
The kids who build robots used the CAD program to get 3D images of how the chariot of sorts could work.
